Card battery
The card is a battery-buffered storage medium. The battery must be
changed periodically so that no loss of data occurs. Please note the battery
shelf life which is given on the leaflet accompanying the card.
When the card is inserted in the Liquino a warning is given when the instru-
ment is switched on or when card functions are called up if either the battery
potential is too low or if the date for changing the battery has elapsed.
The battery is located in a compartment at the front of the card. Please read
the accompanying leaflet when changing the battery. Leave the card insert-
ed in the Liquino when the battery is being changed so that the power sup-
ply is guaranteed.
Important: information about the shelf life of the battery refers to a storage
temperature of 25 °C. At higher storage temperatures the shelf life is shorter.
Therefore
do not
• carry the card on your body
• store it near a heating source
• expose it to direct sunlight.
Write protection
The write protection of the memory card prevents all functions which write
on the card (store methods, delete methods, change directory, create direc-
tory, delete directory, backup, format card, alter battery change date). Read-
ing functions are possible.
The write protection is switched on when the slide at the front edge of the
card is in the right-hand position.
